flutter_blue's Issues

BluetoothDescriptor isNotifying throws error: out of range

This error can be found on the example of this package. At the devicescreen, notifying values' status are not correctly displayed.

When I call isNotifying to check if it's notifying, it always returns false so I've checked if any error was occuring by printing error, and checked 'out of range' error was occuring. Probably the cccd.lastValue is empty.

I tried reading the descriptor(0x2902) of the characteristic to get the correct notifying status, but failed since reading multiple descriptor at once is unavailable. It throws descriptor read error, that reading descriptor while other descriptor is being read.

Invalid Data safety section - Usage of ACCESS_FINE_LOCATION

Hi there,

I am currently using v0.11.0 of your fork in my app. Now with every release I get a warning that I am violating the new data safety section (visible from Feb 2022, compliance require from April 2022). The issue is

Data sent off device undeclared in Data safety form: Location Data Type - Precise Location

which to my knowledge should be related to <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> in the AndroidManifest.xml.

Since I can ensure that the physical location is actually not required, is there a way this can be removed from the plugin and added as an installation step to the plugin? I would like to avoid having to declare I am using the user's precise location since I am not actually using it and it may concern users.

Has anyone else experienced this?

Thanks!

Edit: Just realizing this PR and this link. Looks like ACCESS_FINE_LOCATION is required.... Can anyone confirm this?

Characteristic Future never return

In case i try to read or write a characteristic on a glucose meter and after PIN dialog popup, if i cancel it or write in it a wrong PIN, Future await never return.

java.lang.ClassCastException on device.connect() - version 0.13.0 specific

Hi! I'm experiencing an issue when I call device.connect() in version 0.13.0. Please have a look at the log:

This issue doesn't happen in version 0.12.0. My testing device is Android 8.0.0. Could anyone provide any advice on how to deal with it? Thanks in advance!

CentralManager Init: Background Usage and API MISUSE

Previously, pauldemarco#191 had changes for background usage on iOS and Android.

https://github.com/boskokg/flutter_blue/releases/tag/0.11.0 claims Android background usage was added in this repo, but no PR number was referenced and the iOS changes are not present currently.

There are some conflicts with master now because the centralManager initialization was moved to the first handled message. This causes a race on whatever first message is received and startup of CoreBluetooth. The workaround is to make a call like flutterBlue.instance.isOn().

The reason for this change was to delay requested permissions popups from firing as soon as the app opens the first time, so it was a necessary but undocumented regression.

Minimum iOS Deployment target is 10.0

Some of the CoreBluetooth bindings are minimum of 10.0 for IPHONEOS_DEPLOYMENT_TARGET. The Android minimum sdk version is documented on the README. The default for a new flutter application is 9.0.

Instructions for updating the deployment target are documented here: https://docs.flutter.dev/deployment/ios#review-xcode-project-settings

Example Android Build Fails with :flutter_blue:compileReleaseJavaWithJavac

See capture below. I've done some Googling but lost on this one. Build host is macOS. iOS and macOS builds and run fine.

I did find flutter/flutter#23131 (comment) and pauldemarco#346 but they are both very old and just suggest upgrading the Gradle version to a version already surpased or downgrading Flutter Blue.

An exception has occurred in the compiler (1.8.0_242-release).

Example app is not working on macos

The example app is somewhat broken on macos.

The scan finds devices, but connection button is disabled for some of them and service UUIDs are somewhat off.

Add getUuids()

You should return the result of getUuids() during device discovery: failing this makes it practically impossible to decide which devices a particular use case scenario is interested in.

I'll try to come up with a PR but I had bad luck with protobuf generation on Windows earlier, this seems to be a recurring problem...

Cant find phones on scan result

I am trying to connect two phones through this library. I have two Pixel 4a phones which I am trying to connect to each other. But neither of them appear on the scan result. Is there something specific I need to do to make them visible, other than turning on the Bluetooth adapter?

Bonded devices

I have bonded and connected the device, when I try to discover services I got this in logs, but services areempty.

With Android 12 not find all bluetooth devices

I tried this fork in my app and with your example with my Pixel 4 running Android 12 and scan results are quite less rather than pauldemarco plugin.
I found that the problem is on permissions: ble scan in Android 12 doesn't need permission for access_fine_location but if you don't allow this scanning lacks some devices.
I had modified AndroidManifest.xml in:

<uses-permission android:name="android.permission.BLUETOOTH_SCAN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

<!-- Request legacy Bluetooth permissions on older devices. -->
<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

and giving manually location permission scan result is right.
Ble devices that is not recognized are some old Sensoro Beacons, maybe they will be never supported in Android 12.
Hope this helps.

BluetoothDeviceState return connected when device disconnected

Future<List> connectedDevices sometimes return the result with disconnected devices but show connected state, and when I want to discover services I got this:

deprecated API

this lib still up to date? I found the deprecated API, can you fix it?

.pub-cache\git\flutter_blue-a7fa5410b66cabdc3f12e7d74375db3477a70c85\android\src\main\java\com\pauldemarco\flutter_blue\FlutterBluePlugin.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

flutter_blue:
    git:
      url: https://github.com/boskokg/flutter_blue/
      ref: 0.13

I'm using flutter 3.3.4

The ios name is incorrect

The ios name is not accurate, similar to a cache problem. After the connection is successful, the user disconnects and scans the name again

pubspec setup in README.md

Thanks for maintaining this plugin. It might be worth adding the pubspec setup in the main README (not everybody is well aware on how to use git dependencies):

flutter_blue:
  git:
    url: https://github.com/boskokg/flutter_blue/
    ref: 0.11.0

(Yes I know I could de a PR but well...thanks in advance!)

Crash while scanning...

At this point this a blocking issue for me. The app is crashing without stopping in the debugger even when trying to catch all exceptions.

I updated to flutter 2.8 recently (I'm not sure if that matters)
Android Studio recently updated to 2020.3.1 Patch 4
Android minSdkVersion is 27
targetSdkVersion is 31 (or 30)

iOS BluetoothState.off initially even if bluetooth is on for version > 0.9.0

I get the wrong status initially on recent releases.
I need to toggle the BT off and on to get the correct status.

EDIT: This is for all releases after 0.9.0
Only change I can see that may be related is the update of RXDart to 0.27.
Since I'm having issues with state it is not unreasonable to suspect this is involved.

Tested on multiple iOS devices running 15.2, both under debugging and distributed.
Tested on Android and the issue is NOT reproduceable there.
